Application filed December-17,1909. Serial No. 533,621.

,Toall 'whom may concern:

Be it known that I, CHARLES J. MAGKERni,

a chief machinists mate, U. S. Navy, citizen of the United States7residing at Newport News, in the county of lVaiwick and State ofVirginia, have invented certain new and useful Improvements in Valvesfor- Steam-Traps and the Like, of which the following is aspecification. I

My invent-ion relates to certain new and 4 useful improvement in steamtraps, and the object of my :invention is to provide a trap of thischaracter which will be simple` in construction, positive and accuratein its operation, composed of but fewpaits and not likely to get Aout oforder.

lVith these and other object-s in View my invention consists incertainconstructions, combinations and arrangements of parts thepreferred form of which will be first described in connection with tli'eaccompanying drawings and then the invention particularly pointed out inthe appended claims.

Referring to the drawings wherein the same part is designated by thesame reference numeral wherever it occurs, Figure 1 is a centrallongitudinal section of the trap constructed in accordance with myinvention, showing the parts in the position they assume when the drawoil valve is closed; Fig.'2 is a similar view showing however the drawoi' valve open.

Itis desirable in steam traps of the type in which my invention isembodied that a certain amount of water be retained in the trap 'at alltimes, and that as soon as the water passes a predetermined level it bedrawn ofi' until said level is again obtained.

3 designates a casing for the trap which is closed at its upper end bythe head 4.

5 designates a pipe which extends from any main oi' other vapor carryingpart from which the condensed liquidl is to be trapped. This pipe isshown asfbeing provided with a valve 6 and extends into-the top of` thehead 4.

7 is a draw off pipe which extends through the head 4 down near thebottom of the casing 3. This pipe at its lower end is provided with anydesired form of valve structure 8, that 'shown for the sake ofillustration being the same as illustrated in my pending application No.512,722, filed August 13, 1909, it only being necessary that this valvebe of such a type that it can be opened and closed by the oscillation ofan arm 9 pivoted Vagain niovefth'e parts to the position shown at .oneend to a standard A10 formed on the f valve ;8. Asshown thevalve isprovided.

`with a reeiprocatin'ggate or plate 11 which is connecte to the rod 9,so that when the ,rod Ais raised the plate will be' raised and the valveo cned, and when the rod isloweredthe v ve will .be closed 12.designates an open top rece tacle which v is smaller than the casing 3.nnected to this receptacle is a rod l'which, in the rticularconstruction shown, isconneeted to the bottom of the rece taele by a nut14 clamping the bottom 0, the receptaclebef tween it and a collar 15formed at the lower `end of the rod.

Tlie'rod extends out through the'stuing box 16 inthe head 4 ofthe'casing, and is connected by a link 17 to one end of'aflever 18pivoted at 19 to a standard 20, projecting' from the cover 4, said leveralso carrying the adjustable weight 21 which can be slid along `i thelever andv securedin position'b sired means as a set screw 22. Tli tacle`12, as will be seen from the drawings, receives all liquid through thepipe 5.

' 23 is a rod pivotally connected at its lower end by means o f a pin 24passing into -a slotf '25 formedadjacent the end of the lever 9.

This rod at its upper end passes through a flowing into the Atrapstuffing box 26 formed in thehead tand pipe 5 is received in thereceptacle 12, which is held in the position shown in Fi'g. 1 until theaccumulation of water therein counter# 'is connected 4by meansof a link27`to the lever 18 on the opposite side of the pivot 19 balances theweight `21', whereuponthe receptacle will move down, pulling down the,

lever 18 which will pullup on the rod 2 3 and through the lever 9 openthe' valve, permitting the accumulation of water in. the

trap to pass out through the ipe 7. As soon as the weight of-water in te receptacle is insuflicient to counterbalance'the weight-21 the partswill be returned to theiroriginal-- osition, as shown Fig. luapdwillreri'i'ain 1n such position until there isa suflicient accumulationof water in the `,receptacle to in Fig. 2, opening the valve 8. A

4I realize that considerable variation .1s possible in the details ofconstruction and arrangement of parts without de arting from the spiritof my invention, 'an I therefore do not intend to limit myself to thespecific form shown anddescribed.

What I claim 'as new and desire to seoure by Letters Patent is:

1. In' a, steam trap, the combination with a closed casing, of areceptacle-within the easing and separated therefrom, a gated valvewithin the reoeptacle and out. of 0011-' I tot therewith, a lever withinthe receptacle and connected tothe gate of said valve for operating it,an overflow pipe leadingifrln said valve, a lever exterior to thecasing, a. rod connectin receptacle, an a second rod connecting the-ie'xterior lever with the valve lever.

2. In 'zt steam trap, ,the combination with l e closed casing, ofereceptacle within said .casing and separated therefrom,` a `valvewithin said receptacle and out-of contact Y.

therewith, lan overlowppe leading from said valve, a'. 1ever 1n ountedon th outside ,level-Q Ae rod connect-in the exterior lever with theweight adiustably mounted on said lever.
